ri esh'sai- To all wliojm z rihylc dnc ern:

' Be it known" that I, GEORGE DARLQW, a citizenof the--Unite'd' States, residing in lViiifredQt-ownship, in, the county of Lake and Stateiof South Dakota, have invented certain new, and: useful Improvements in ers, of which the following is a.

BundleLo I d specification.

- This invention relates to harvesting de-' vices for-handling grain in sheaves, and has broadly foritsobject' theprovision of an 2a of thischaracter having means operated .by

- the driver for raising. the-pick up cylinder improved dev'ice adapted to be drawn over a field aftdr. the "grain has been cut and tied in bundles an'dwhich will pickup the bundies and, loadztheminto a wagon traveling beside the device-r An importantobjectis the provision of a leader :of this. character provided with a novel pick up cylinder embodying. movable teeth and automatic, -operating mechanism tor protecting the.teeth-to engage the buns dies and for retracting theteeth out of engagement therewith: at a predetermined Another object isthe provision of a loader considerably above the ground to avoid ob- I st'ructions such as. stones or stumps which 30 would injure the mechanism. I

Still another object is the provision of a novel and peculiar construction-whereby the a portion of the frame supporting the pick up cylinder may be quickly moved by the driver relatively to the main frame to permit changing the driving gears for changing the speed of rotation of the pick up cylinder relatively to the speed of travel of the loader, and wherebyjthe device may be thrown quickly out of gear while traveling.

- A. further object is the provision of means for discontinuing the discharge of bundles whenthe receiving wagon is unable to keep in proper relation with the loader as in following a, crooked row or-making a turn or curve, and at the same time have the pick up cylinder and the receiving conveyer continue operating. and the discharge conveyer receive and hold the bundles until the wagon is in a position to receive them.

ciency in service, and the general improvement of the art .will be carefullybroughtout n the iollow ng description and illustrated in the accompanying drawings, in which? Figure 1 is a top plan view of the loader,

F ig.2 is a side elevation with the frontdrive wheel removed, Fig. 3' is a rear elevation, Fig. 4: 1s a iragmentary elevation of the op posite side, Fig. 5 IS a cross sectional View on the line.5 5 of Fig. 1, and Fig. 6 is a sectional view on the line 66 of Fig. 5.

Referring more particularly to the drawin'gs, the numeral 1 designates the longitudinal bars of the main or rigid frame which are provided upon their forward ends with bearing blocks 2 journally receiving the main or drive axle 3 carrying thetraction wheels 4 provided with the usual ratchet The bars 1 support a platform 5 upon the rear end of which are revoluble standards-6 carrying axles 7 provided with 'wheels 8. An auxiliary or drivers platform- 9 is supported above the main platform 5 by standards 10 and carries the usual seat The movable frame comprises bars 12 and 13 spaced apart as shown and formed separately or integrally by bending, and in either case channel bars being preferably nally receive the axle 8, while other bearing blocks 15 are rigidly secured between 16 of the pick up cylinder 17. The pick up cylinder 17 comprises outer heads 18 formed as sprockets and an intermediate disk 19, all secured upon the axle 16. A plurality of rods 20, 21, 22 and 28 extend through the-heads 18 and the disk 19, and carry upon their respective ends,pinions 24, 25, 26 and 27, each having preferably eight teeth. A cylindrical housing 28 is secured upon the bars 12 and 13 concentric with the axle 16 and has secured upon its inner periphery a ring 29 provided with sets of teeth 31' and 32, the set 30 comprising four used. Bearing blocks 14: are slidably disposed between the bars 12 and 13 and jourteeth and the sets 31 and 32 comprising each two teeth. These sets of teeth are adapted to mesh with the pinions 2- 25, 2 and 27 at different stages of rotation of the pick up cylinder as will be hereinafter more fully described. The rods 20,21. 22 and carry a plurality of fingers .53 adapted to engage bundles of grain and lift them from the ground. The relative positions of the pinions. sets of teeth on the ring 29. and fingers should be asshown in Fig. (3. The pick up cylinder 17 is rotated by means of gears 3-.t on the drive axle 3 meshing with gears on the cylinder shaft 16.

As the cylinder 17 rotates, the rods '20,

21, 22'and "23 will be carried around with carrying the fingers 33. The rods and nngers being adjusted in the first place to occupy the relative positions shown, as the rods 20. 21, 22- and 23 approach the downward limit of their movement. the pinions will successively engage the teeth 32 and be rotated a quarter turn moving the rods 20. 21. and 2 3 so that the fingers 33 will extend substantially horizontally forward. As the rods then approach the lower forward limit of their movement, the pinions will engage the teeth 31 and be moved another quarter turn to still extend in the same position relative to the ground. In these two positions the fingers will engage bundles of grain and carry them up. As the rods approach the upper forward limit of their movement, the pinions will successively engage the teeth 30 and be rotated a half turn, thereby causing the fingers to swing down out of engagement with the bundles, thus allowing the bundles to fall upon the receiving conveyer designated as a whole by the numeral 36. As the rods are moved to their upper rearmost positions they will retain their preceding positions, that is they will hairg-straight down. As the rods then approach their lowest rear positions the pinions will engage the teeth 3'2, thus mtwing the rods and consequently the teeth as first t lescribedi In order that the rods may be prevented from undesired movement and still be allowed-to move-at the proper time, I provide upon each rod a spider 37 comprising pref erably four arms carrying upon their ends rollersiES engaging against the inner periphery of thehousing QS'and preventing the rods from rocking. in order that the rods may be permitted to rock at the proper time. I. provide depressions 39 in the periphery of the housing adjacent the sets of teeth 30. 31 andfii. so that as the pinions engage each. set of teeth the rollers will enter the depressions and allow the rods tov turn.

The receiving ctmveyer 36 onto which the bundles are deposited comprises a pair of rearwardly inclined bars T0 bolted upon the -hopper secured upon the '77 bolted onto the platform bars 12 and braced by bars 41 as shown. Bearings 42 are secured upon the bars l0 and journally receive a shaft 4 carrying at its center a pulley or roller -i'-l' and at its ends sprockets 1L5. Chains to are trained about the sprockets 1S and 4:5 and a belt t7 is trained about the rollers 19 and H. Slats :18 are secured upon the chains and belt and are preferably provided with spikes 4!) adapted to penetrate the bundles which are deposited upon the conveyer. As the pick up cylinder 1T rotates, the conveyer 36 will be driren by virtue of the sprocket and chain connection The discharging mechanism C OI DPIlSQS a platform 5 rearwardly of the convcyer 3G and leading to a chute :31 containing a spiked and slotted conveyer 52 inclined upwardly for discharging bundles into a suitable wagon traveling beside the loader. The shafts 53 and 5% at the ends of the conveyer 5:! are provided with sprockets 55 and 56 about which trained a chain The sprocket 56 is loose upon the shaft 5% and has formed thereon a clutch member 58 engaging a clutch member 59 splined upon the shaft ST. The two clutch members are held normally in engagement by a spring ('10 surrounding the shaft 54 and abutting against the clutch member 59 and a bearing 111. The clutch member 59 has a sprocket (12 formed thereon about which is trained a chain (33 trained about a sprocket (H secured upon a short shaft journaled in a bearing htrsecured upon the platform The sprocket til has formed thereon a bevel gear 67 which meshes with a crmvn'gear (38 secured upon the lower end of an inclined shaft (39 journaled through a bearing 70 secured upon the hopper 5b. The upper end ofthe shaft (19 is connected by a universal joint 71 with the lower end of a square shaft 72 upon which is slidably mounted a. bevel gear T3 meshing with the bevel gear 74- secured upon one end of the shaft A bracket 75 is secured upon the adjacent bar 40 and extends under the bevel gear 73 for holding it in mesh with the gear 74-.

The loader is drawn by horses hitched to whittletrees 76 connected with a draw beam 5. one horse being used on each side of the machine. As theloaderis drawn over a field; the bundles of rain will be picked up by the cylinder 1t and deposited onto the conveyor 36 as previously described' The bundles will fall from the top of the conveyer lli into the hopper SO'and consequently onto the conveyer 52 which is driven by'the gears Tl and T3. shafts T2 and). gears'tiS and (17, chain (33. clutch members 59 and. and chain 57. The bundles will be carried upwardly by the conveyer 52 and dumped names into a suitable wagon'travelingwbeside the device. 1 In making turns it is naturally impossible for a wagon to maintain its-proper place besidethe machine to receivejbundles picked vup. In order to permit the-loader to continue to pick up bundles I and hold themagainst. discharging until the wagon can re- -'sume its place, I provide a footi'pedal 78 the clutch member '58, thus rendering the operate to discharge the bundles.

Thelower endof the lever 79-is fOrkedand' disposed in a groove 83- in the clutch member 59. When the driver pushes the pedal 7 8 forward,-the clutch member 59 will be moved backagai'nst the resistance of the spring 60 and out of engagement with conveyor 52 inoperative and allowing .bun dles picked u to be retainedin the hopper 50; When t e accompanying wagon; has resumed its proper place, the pedal 7 8 is released, whereupon the conveyer 52 will again When the driver seesthatthere are obstructions in front of the machine which might cause injury, it is necessary that the "pick up cylinder be raised to avoidgthe ob'- structions- In order to accomplish this, I
